SAW-VISE.

SPECIFICATION forming part of Letters Patent No. 757,320, dated April12, 1904. Application filed July 8, 1903. Serial No. 164,720. .(Nomodel.)

To all whom it may o0ncern.-

Be it known that I, MARTIN LAURSEN, a citizen of the United States,residing at Roches ter, in the county of Olmsted and State of Minnesota,have invented new and useful Improvements in Saw-Vises, of which thefollowing is a specification.

My invention relates to improvements in' different views.

The numeral 1 designates a U-shaped member having parallel arms 2 and 3.The arm 2 bears a cross-bar 4:, which isshaped to form the fixed jaw ofmy vise. A bench-clamp 5 is connected to the upper end of the arm 2 andis provided with a set-screw 6 for use in securing the vise to asuitable base or support. A T-shaped member 7, havinga slotted stem 8and a cross-bar 9, is pivoted to the upper end of the arm 3, with thearm 3 fitting within the slot 8 in the stem. The cross-bar 9 is shapedto form the pivoted jaw of my vise.

1 It will be noted that the clamping-faces of the parts or jaws 4 and 9are adapted to engage the saw blade, held therebetween at points onebelow the other, to provide thereby for the lessening of the vibrationofsaid sawblade when operating upon the last named.

Pivoted to'the extremities of the slotted stem 8 by its arms 1O is ayoke-shaped mem ber 10, having a cross-bar 11 connecting the arms 10. Anaperture 12 is formed in the cross-bar 11 to accommodate a set-screw 13.

A rounded lug formed on the lower end of the arm 3 has an indentation14: formed in the face thereof to serve as a seat for the inner end ofthe set-screw 13 to hold it against slipping.

In using my vise the bench 5 is secured to some suitable support bymeans of the screw 6. The saw to be filed is then inserted between thejaws i and 9 and the yoke-shaped clamp 10 turned up until the lower endof the screw 13 engages the indentation 14, after which the screw 13 istightened to actuate the jaw 9 and clamp the saw.

It should be noted that connecting the clamp as near the jaw as possiblemakes a very steady vise.

I do'not wish to be limited as to details of construction, as these maybe modified in many particulars without departing from the spirit of myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A vise of the character described, consisting of a stationary jawmember, a bifurcated movable jaw member pivoted, a short distance belowits upper end, to the corresponding end of one arm of said fixed jawmember, said stationary jaw having a projection adjacent the lower endof the removable jaw and a yoke pivoted to the lower ends of the legs ofsaid movable jaw member, and equipped with a binding-screw arranged tobear upon said arm adjacent the projection, whereby, by slightly turningsaid screw in one direction, said yoke may be moved upward to quicklyrelease or open the jaw members.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
